Household usage tracker
Record a supply when you start it, mark it finished later, and turn elapsed time into a practical usage rate. This is a small decision tool—not pantry inventory or a grocery list.

How averages are calculated
One completed period shows how many days the recorded amount lasted, plus average use per day and week. When the same item name and unit have several completed periods, the tracker combines their total amount and total elapsed days. That weighted history avoids treating a short and a long period as equally representative.
Use consistent names and units—“Paper towels” in rolls each time, for example—so records group together. A cost is optional; when recorded, the history can also estimate cost per day.
